WINDOW SCREEN.

Application filed June 14, 1922. Serial No. 568,256.

To all whom it may concern Be it known that I, MATTHIAS A. DIETRICK, a citizen of the United States, residing at Patton, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Window Screens, of which the following is a specification, reference being had to the accompanying drawings;

This invention relates to certain improvements in window screens, and has relation more particularly to a device of this general character of a rolling type and it is an object of the invention to provide a novel and improved screen embodying a flexible fabric adapted to be disposed across a window opening together with a container or housing for said flexible element when the same is in inoperative position. I

Another object of vide a novel and improved device of this general character embodying a housing or casing in which the screen or kindred flexible fabric is adapted to be housed together with The novel features ,of my invention will.

hereinafter be definitely claimed.

In order that my invention may be the' better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is an elevational view illustrating a screen constructed in accordance with an embodiment of my invention andin applied position;

Figure 2 isa sectional View taken substantially on the line 2 2 of Figure 1;

Figure 8 is an enlarged sectional View taken substantially on the line 33 of Figure 1; l

Figure 4 is a jview partly in section and partly in top plan, illustrating the device as herein set forth;

the inventionis to pro- Figure 5 is a sectional view taken substantially on the line 55 of Figure 1;

Figure 6 is a fragmentary elevational view illustrating a modified form of the invention;

Figure 7 is a fragmentary View in top plan of the structureillustrated in Figure 6;

Figure 8 is a fragmentary view in elevation illustrating a further embodiment of my invention; and Y Figure 9 is a view in perspective of a tool for eflecting the desired rotation of the rod comprised in the housing or receptacle.

As disclosed in the accompanying drawings, S denotes the sill of a window frame or casing and J the jambs associated therewith 1 denotes a plateheld to the sill S adjacent a jamb J by a screw 2 or the like, said plate 1 being herein disclosed as substantially semi-circular in formation with its straight edge opposed to the amb J and substantially defined by an upstanding flange 3. Extending from an end portion of the straight edge of the plate 1 and disposed toward the jamb J is a finger 4 possessing a certain degree of inherent resiliency and which has its outer or free 'end portion disposed on a predetermined upward curvature.

5 denotes a second plate having one end provided with an upstanding flange 6, said flange being pivotally connected through the medium of the bolt 7 or the like with a jamb J and at a point preferably above the lower or meeting rail of the upper sash when said sash is in its closed position. This plate 5 overlies the portion of the sill S between the associated jamb and. the plate 1 adjacentthereto.

Theside marginal portions of the plate 5 are provided with overlying flanges 8 which provide guide-ways for the sliding lock plate 9. This lock plate 9 is provided with a but .tonhole slot 10, the larger end of which registers with an opening 11 in the plate 6 upstanding flange 12 to facilitate the manipulation of such plate. 9

, Hdenotes a housing or container which is adapted to fit substantially snug between the sill S' and the upper plate 5. This housing or container H is substantially rectangular in cross section and the body portion 15 of this housing is formed of a single sheet of material bent into requisite form, with 'thelongitudinal edges of said strip, in the completed device, separated to provide an entrance slot 16. These longitudinal edges are also defined by the returned flanges l7. Coacting with the opposite ends of the bodyrl5 of the housing or receptacle H are the caps 18, said caps snugly fitting within the end portions of the housing or receptacle H and to facilitate such engagement of the caps, each of the caps is defined by the marginal flanges 19, certain of said flanges interlocking with theflanges'l'? whereby the body 15 of the housing or receptacle H is maintained in fixed formation.

The caps 18 at the axial centers thereof are provided with openings 20. Disposed lengthwise through the housing or receptacle H is a rod" R herein disclosed as angular in crosssection and having one end portion upset or otherwise enlarged as at 21, saidenlargement seating within a pocket 22 formed in the bottom cap 18 so that when the housing or receptacle H is in applied or working position the rod R will offer nohindrance or obstruction. The rod 23 denotes a screen fabric of requisite dimensions, and one end portion of said screen has secured thereto a binding 24: of textile material, said binding extending beyond the adjacent margin or edge of the sheet 23, said extended portion being formed, through the instrumentality of the row of stitching 25, into a casing 26 through which the rod R. is directed. By fact of thebinding 24 beingof textile fabric and the rod B being angular in cross section, turning" movement of the rod R in one i r direction will result in the requisite winding j largedportion of the slot 10 from'registering with the opening 11 to permit the desire d rotation of the rod R and also to cause the restricted portion of the slot 10 to receive the rod to hold saidrod'R against rotation. lVhile any means that can be employed with'facility and convenience may be employed for rotating the rod R, I prefer to employ a wrench W of the type illustrated in the accompanying drawings.

The end marginal portion of the screen fabric 23 remote from the binding 2 is secured to an angular plate 27 of a length coextensive with the width of the fabric 23. The plate 27 is preferably substantially L-shaped in cross section and when the housing or receptacle H is in applied posi tion and the screen fabric 23 disposed across the window opening, a fiange of said plate is engaged with the inwardly facing hooks 28 carried by the jamb J remote from the applied housing or receptacle H.

In applying my improved screen, or more particularly the housing or receptacle-H, the upper extended portion of the rod R is disposed through the opening 11 in the plate 6 and through the enlarged portion of the 85 slot 10 in the lock plate 9 and with the.

housing or receptacle H. angularly disposed with respect to the jamb J, which is permitted in View of the fact that the plate 5 is supported by its associated jamb Jfor swinging movement about a horizontally disposed axis. After thi arrangement, the lower portion of the housing or receptacle H is swung downwardly, the lower end readily passing .over the finger 4t, owing to the resiliency of said finger. This permits the housing H to be supported directly upon the sill S with the finger 4; extending slightly abovethe lower end of said housing or receptacle H whereby the same is effectively maintained in applied position.

In lieu of the screen fabric 23, a Woven or textile fabric 23*, as illustrated in Figure 8, may be employed, and especially when it is desired-that the device he used as a ventilator as in the winter time.

With a screen constructed in accordance with an embodiment of my invention it will be readily understood that thesame may be applied in the working position and when the fabric 23 is not in use, the same may be readily stored within said housing or receptacle H and held or supported by the associated jamb J. Under these conditions the housing or receptacle H forms no undue hindrance to the window opening.

lVhen it is desired to employ 'my improved device only in connection with one of the sashes of the window, orwhen the .screen fabric or ventilating fabric is of a width less than the full extent of, opening movement of the coacting sash, I provide a supporting plate 28 which has a longitudinal marginal portion overlying a parting strip 29, while the opposite longitudinal marginal portion of the plate 28 is provided with an inwardly directed flange 30 which contacts with the adjacent jamb J; Holdingscrews 31 are disposed through the plate 28 and engaged with the jamb J although it is to be understood that this plate 28 may be held in applied position in any manner which complies with the requirements of practice. One end portion of the plate '28 has operatively engaged therewith a plate 5 constructed as hereinbefore referred to and having the same parts coacting therewith. The opposite end portion of the applied housing or receptacle coacts with a plate 1 or more particularly a finger 4, as hereinbefore set forth.

What is claimed is 1. A screen structure for windows comprising a casing containing a roller having a screen Wound thereon, the casing having a slot through which the screen may be drawn to be extended across the window opening, and means for mounting said casing on the window frame, said means comprising an ear at the upper end of the casing pivotally mounted upon one side of the Window frame, a plate secured upon the window sill and formed with an upstanding flange arranged in spaced parallel relation to the adjacent side of the window frame, and an upwardly extending spring tongue on said plate engageable by one side of said casing for maintaining the casing in vertical position against the side of the window frame.

2. In a device of the character described, an upright casing having a slot therein, a roller journaled Within said casing and having a screen Wrapped thereon, the casing being formed with a slot through which said screen may be drawn, a hearing at the lower end of the casing for the lower end of the roller, the upper end of the roller being rectangular in cross section, a cap on the upper end of the casing having an opening through which said roller is rotatable, guides on said cap, and a plate slidable within said guides and having a keyhole slot accommodating the upper end of the roller, said keyhole slothaving an angular portion of a size to receive the roller end and hold the roller against rotation and further having an opening of such size as to register with said first named opening to permit rotation of the roller.

In testimony whereof I hereunto aflix my signature.
